DEEP-MINE OR RELAY PUMP.

SPECIFICATION forming part of Letters Patent No. 621,667, dated March 21, 1899.

Application i'lled July ll. 1898. Serial No. 685,671. (No model.)

To all whom t may concern:

Be itknown that I, GEORGE S. HERBOLSHEI- MER, of Denver, in the county of Arapahoe and State of Oolorado,have` invented a new and Improved Deep-Mine or Relay Pump, of which the following isa full, clear, and exact description. p

The object of the invention is to providea "new and improved deep-mine or relay pump arranged to permit of pumping water out-of a mine-shaft at one or more levels at the same time, the pump being arranged to allow the operator to connect or disconnect any one of the individual pumps whenever desired.

The invention consists ofnovel features and parts and combinations -of the same, as will be fully described hereinafter and then pointed out in the claim.

Reference is to loe-had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the improvement as applied and with the mine in section. Fig. 2 is an enlarged sectional pla-n view of one of the pump-cylinders and a plunger operating therein. Fig. 3 is a sectional side elevation of the same, and Fig. 4 is an enlarged sectional side elevation of the duplex pumps. The improved device for raising water from mine-shafts and levels is provided with a main pipe A, extending in the mine-shaft B and connected with a branch pipe O, containing a check-valve O', said branch pipe extending through a level B', terminating in a sump B2.

The branch pipe O connects with a pipe D, eX-

tending in the sump B2, and said main pipe A, as well as the pipe D, is provided with double or duplex single-action pumps E E' E2, respectively, it being understood that the connection of the pipe O with-the main pipe A is between the two pumps E E'. The several pumps E E E2 are alike in construction and it suffices to describe but one in detail, special reference being had to Figs. 2, 3, and 4.

Each of the pumps is provided with two cylinders F F', connected at their lower ends by pipes G G', respectively, with a chamber I, connected with the pipe A, and similar pipes G2 Gs lead from the upper ends of the cylindersF F', to a discharge-chamber I. A pipe J connects the two chambers I I' with each other, so as to render the pipe A continuous.

In the pipe J is a valve J', which is normally closed, while the valves H H' in the pipes G G' are normally open; but when it is desired to cut out the cylinders F F' then the valves H H' are closed and the valve J is opened, so .that water can pass directly through the chambers I I and pipe J and the pipe A. The chambers I I' are providedwith suitable plugs I2 for giving access to adjacent valves.

In the lower end of arranged check-valves K, and similar checkvalves K' are arranged on the upper ends of the pipes G2 G2. In the cylinders are mounted to reciprocate plungers L L', respectively held on plungerrods L2 L3, extending upwardly'through stuffing-boxes secured to the upper ends of the cylinders. The outer ends of the plunger-rods L2 L2 are secured to brackets N N', respectively, bolted or otherwise the length of the shaftB and guided in suitable bearings O2, attached to the cylinders. The upper ends'of the rods O O' are connected with a suitable mechanism such as a pump, for instance-for imparting a reciprocating motion to the said rods simultaneously, but in `Vopposite directions thereto, to cause one of the plungers to ascend while the other descends to make the pump a duplex singleaction pump.

In order to transmit the motion of the side rods O2 O4 for working the plungers of the pumps E2 in the sump B2, I provide the following device: On the rods O O' are arranged turnbuckles P P', respectively, pivotally connected by pitmen Q Q' with diametrically opposite wrist-pins on a crank-wheel R, journaled onv a suitable stud carried bythe 4pipe A, and said crank-wheel R is connected at its wristpins by links S S' with similar wrist-pins on a crank-wheel R', arranged in the level 'B' over the sump B2. This wheel R' has its wristpins connected by pitmen Q2 Q3 with the rods O3 O4, previously mentioned, so that the upand-down motion given tothe rods O O' is transmittedby the pitmen Q Q', the wheel R, the links S S', the wheel R, and the pitmen Q2 Q8 to the rods O3 O4 to actuate the plungers in the pumps E2.

the cylinders F F' are f .fastened to rods O O', extending throughout IOO It is evident from the foregoing that when I the several valves J' are closed andthe valves H H' are opened in all..of the pumps and a reciprocating motion is given to the rods O O', as previously explained, then all the pumps are set in motion simultaneously and water is pumped from the mine-shaft, as well as from the level and its sump, to the outside of the mine. By opening the valve J and closing the valves H H' of any one of the pumps the operator is enabled to cut out a level or main shaft, as desired, so that water is only pumped from the main shaft or from one of the levels, as desired.

It will be seen that a pump constructed in the manner described may be used for shallow-well pumping and give excellent satisfaction on account of the large amount of water raised by the pump with the greatest ease. Any one of the pumps can be readily arranged for any kind of work, and the pumps are not expensive to build or keep in repair and will pump any amount of Water with any kind of power. When used in a mine, they take up very little space, cannot be iiooded, will not overheat a mine, and can be placed at any angle and repaired without stopping the entire system.

In order to assure long life to each plunger in a pump, I prefer to construct vthe same as shown in detail in Figs. 2 and S-that is, I provide the cylindrical plunger-body L4 with a spider, in the middle of which screws the lower end of the plunger-rod L2, and on the said body is secured a bail L5, engaged by the rod L2, as is plainly shown in Fig. 3. The valves L6 are hung on pintles L7, carried in eyes formed on the body L4 and engaging the lower end of the plunger-rod L2, so as to hold the several parts securely in position. The valve-seats for the valves L6 are formed with grooves L8, adapted to contain water to cushion the valve and obviate the necessity' of providing a special packing for the valves.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- A deep-mine or relay pump comprising a series of pumps arranged in successive pairs at different elevations, Va common water-main, each pair of pumps comprising two cylinders having suction and discharge connection with the water-main, a cut-off valve in each suction connection, a by-pass for the main pipe having a cut-o valve therein, a piston in each cylinder havinga rod extending through a stufling-box in the upper end of the cylin-
